Ethereum Mainnet

Definition ∞ Ethereum Mainnet is the principal, operational blockchain network where all verified Ethereum transactions and smart contract code executions occur. It serves as the definitive public ledger for the Ethereum ecosystem, processing real-world value transfers and decentralized application interactions. This network stands as the live version, distinct from experimental or testing environments.
Context ∞ Reports concerning Ethereum Mainnet often highlight network performance metrics, such as transaction throughput and gas fees, or significant protocol upgrades. Its ongoing evolution, including shifts to proof-of-stake and subsequent scaling solutions, remains a central focus in digital asset reporting. The network’s stability and capacity directly influence the broader decentralized finance landscape.
